TLDR
In this article, a hand-held digital camera is used with a workstation that may exist in a commercial image processing service center to perform image processing in real-time single pass image compression.Abstract:
A digital camera system in which capture, processing and storage functions are partitioned differently than in existing systems. A hand-held digital camera is used with a workstation that may exist in a commercial image processing service center. A minimal amount of image data processing is performed in the digital camera, thereby allowing significant digital camera cost reductions due to lower memory requirements, lower processing requirements, and lower power requirements. Real-time single pass image compression techniques are employed within this digital camera to permit rapid gathering and storage of raw or minimally processed image data. The workstation to which the image data are transferred performs the image processing normally done within existing cameras. This processing takes advantage of the increased computational power that is possible to have in such a workstation, compared to that of a small camera, and the increased time over which such processing may be performed.read more

Patent
Image pickup device
TL;DR: In this article, an image pickup device may include an optical system having a distortion that captures a distortion-containing optical image, a conversion unit that converts the distorted image into distortion-free image data, and a distortion correction unit that corrects the distortion of the image data with reference to the additional data.
Patent
Image capturing apparatus and image capturing method
TL;DR: In this paper, a panoramic image is generated from the captured images, and the controller displaces the position of the lens unit or the imaging device at the start of exposure of each image to be captured in a direction based on a direction in which the shooting direction is moved.

Digital camera with biometric security
Eran Steinberg,Yuri Prilutsky +1 more
TL;DR: In this paper, a programmable digital camera requiring a programming password to be entered to access the camera's programmability is presented, where the camera can be operated only for a specified time interval, after which the camera becomes inoperable until the programming password is again entered and the camera is programmed to operate for another interval of time.
